So, CQ python process crashed:

[74381874.518542] python[24842]: segfault at 2736b59 ip 00007f9527a79ffe sp 00007fffd04cf838 error 4 in libc-2.19.so[7f95279e2000+1bb000]

interestingly, a "nearby" processed died too
[74381874.518557] python[24861]: segfault at 2736b59 ip 00007f9527a79ffe sp 00007f9521a3fb98 error 4 in libc-2.19.so[7f95279e2000+1bb000] 


So, i think the problem is super old host. TO be fixed by issue 573492
